Background: Colorectal cancer (CRC) is the fourth most prevalent cancer in the world and is positioned the second most common cancer in the United States. Patients with CRC in Indonesia showed a greater proportion. In Jakarta, 47.85% of CRC cases occur under the age of 45 years. The purpose of this study is to determine metastasis and the factors that influence colorectal cancer patients. Method: This study was conducted retrospectively from January 2003-December 2007 in Cipto Mangunkusumo hospital. Patients are eligible if they underwent colonoscopy, tumor biopsy, anatomical pathology, abdominal CT scan, abdominal ultrasonography, and radiology procedures. Result: Of all 1,615 patients who underwent colonoscopy procedure, 377 patients were diagnosed with colorectal cancer. Subject that met the criteria consist of 86 patients, where 56 (65.1%) male. Most aged 51-60 years old (26.7%), mean age 47.90 ± 14.53 years old. The tumor is most commonly located in the rectum and sigmoid 40 (46.5%), in which 18 (45%) among them had metastasized. Compared with male patients, female patients experienced more metastases, but not statistically significant. Among the patients with metastasized CRC, 42.3% of them < 40 years old, 37.2% patients 41-60 years old, and 29.4% patients > 60 years old. Well-differentiated CRC produce larger number of metastatic cases than poorly-differentiated CRC. Poorly-differentiated CRC tend to produce adjacent metastasis, and also happened in relatively young age in compared with well-differentiated cancer. Conclusion: There was significant correlation between younger age group with a poor degree of histopathologic differentiation. Patients with CRC consist of more male patients than female ones. Factors sex, age group, histopathologic subtypes, and tumor location was not associated with metastasis.
